larisa [96]

Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.
